включиться в кого-н

Dear all, I thought I'd put this to your expertise. The verb 'включться в что' seems to mean 'to enter into something' or 'to join in', but these definitions make little sense in the following sentence: 'Бывает, что в какой-то день известный человек включается в меня и ярчайшей вспышкой открывается с неожиданной стороны'. I can only guess what this means, but I thought perhaps 'sometimes a well-known figure decides to confide in me and, all of a sudden, opens up an unexpected side'. Am I close?

Then it's just a peculiar way of saying: "Sometimes a person of some profile (a celebrity, an "intellectual") begins correspondence with me (by the electronic means of sms-messaging, hence the allusion to "be plugged in"), and publishing such correspondence could change the way the public sees him (her)..."

The general idea is 1) there are men who hold high places (must be the ones who staaart...) 2)they are parts of the system and their jobs are not their inner choice (??); their participation in those systems is part of the bigger game (??) or part of "The Game that is played there..." (??) 3)the author finds something different in those people; he communicates precisely with that something. 4)he regrets that he deletes SMS correspondence with them because --->
5)Sometimes - all of a sudden - he switches on to them and then there is a great light that descends upon him and then they stand in his mind all lit up by that light and he sees them in that light and they are all different in that light and if he published such correspondence the public would surely think differently about those people.
